Description

Die Erfindung betrifft einen Konvektorheizkörper mit von einem Heizmedium durchströmten zueinander parallel verlaufenden, in Einbaulage horizontal angeordneten Rohren, die jeweils in stirnseitig vorgesehene, eine Druckkammer bildende vertikale Sammelkanäle münden.The invention relates to a convector heater with a heating medium flowed through each other in parallel, in installation position horizontally arranged tubes, each provided in the front, a Pressure chamber forming vertical collection channels open.

Derartige Heizkörper sind beispielsweise aus der DE 101 55 989 A1 und der AT - PS 310 383 bekannt. Nicht beschrieben ist darin, wie die vertikalen Sammelkanäle mit den horizontalen Rohren druckdicht verbunden werden sollen.Such radiators are for example from DE 101 55 989 A1 and AT - PS 310 383 known. It does not describe how the vertical Collection channels are connected to the horizontal pipes pressure-tight should.

Herkömmliche Konvektorheizkörper mit parallel zueinander in einer Ebene angeordneten Flachheizrohren werden im Bereich der Sammelrohre durch eine so genannte Materialbrücke verbunden, durch die der Spalt zwischen den Schmalseiten der Flachheizrohre wasserdicht geschlossen ist. Die Sammelrohre werden dabei durch eine um sie umlaufende Schweißnaht mit den Flachheizrohren und mit den Materialbrücken dichtend verbunden. Ein derartiger Heizkörper ist beispielsweise aus der CH - PS 672 951 bekannt.Conventional convector heaters with parallel to each other in a plane arranged Flachheizrohren be in the field of manifolds by a so-called material bridge connected by which the gap between the Narrow sides of the flat heating pipes are closed watertight. The Collecting pipes are thereby accompanied by a circumferential weld around them the Flachheizrohren and sealingly connected to the material bridges. One Such radiator is known for example from CH - PS 672 951.

Ein Heizkörper eines anderen Typs ist aus der CH - PS 592290 bekannt. Hier sind an den vertikalen Sammelrohren mehrere horizontale Flachrohre übereinander und gleichzeitig im Abstand voneinander flachseitig durch Buckelschweißen derart angebracht, dass ein jedes Flachrohr mit jedem Sammelrohr über zwei Öffnungen kommuniziert. Um Deformationen des Flachrohres während der Ausübung des Schweißdruckes zu verhindern, müssen zusätzliche Stützteile in den Flachrohren eingezogen werden, was zu hohen Materialkosten und einer relativ aufwendigen Konstruktion führt.A radiator of another type is known from CH - PS 592290. Here are on the vertical manifolds several horizontal flat tubes on top of each other and at the same time at a distance from each other flat side Projection welding mounted so that each flat tube with each Collector communicates via two openings. To deformations of the To prevent flat tube during the practice of welding pressure, additional support parts must be drawn in the flat tubes, resulting in high material costs and a relatively complex construction leads.

Aus der CH - PS 488 520 ist ein weiteres Verfahren zum Verschweißen von mit ihren Schmalseiten satt aneinander anliegenden rechteckigen Flachrohren bekannt, wobei die stirnseitigen Öffnungen durch einen Deckel, bzw. eine Abschlussleiste verschlossen werden, die senkrecht abstehende Lappen aufweist, welche in die Öffnungen der Flachrohre eingeführt werden und die Abschlussleiste festhalten. Die Naht zwischen der Abschlussleiste und den Flachrohren wird dann ebenfalls verschweißt.From CH - PS 488 520 is another method for welding with their narrow sides full of adjacent rectangular flat tubes known, wherein the frontal openings by a lid, or a Closing bar are closed, the vertically protruding cloth which are inserted into the openings of the flat tubes and the Hold the end bar. The seam between the end strip and the Flat tubes are then welded as well.

Alle bekannten konstruktiven Lösungen zur Bildung von druckdichten Kopfstücken bzw. vertikalen Sammelkanälen erfolgen durch Schweißverfahren ggf. mit eingeschweißten Stütz- oder Verstärkungsteilen. Dadurch entstehen neben durch den durch das Schweißen bedingten höheren Arbeits- undAll known constructive solutions for the formation of pressure-tight Headers or vertical collection channels are made by welding possibly with welded-in support or reinforcement parts. This creates in addition to by the welding due to higher working and

Zeitaufwand, Qualitätsnachteile durch undichte Schweißstellen und durch Verschleifen der Schweißnähte im Sichtbereich der Deckel.Time expenditure, quality disadvantages due to leaking welds and through Grinding of welds in the field of vision of the lid.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Konvektorheizkörper der eingangs genannten Bauart derart zu verbessern, dass die durch das Schweißen bedingten Nachteile vermieden werden.The invention is therefore based on the object Konvektorheizkörper the to improve the type mentioned above such that the. By the Welding related disadvantages are avoided.

Erfindungsgemäß wird diese Aufgabe gelöst durch einen Konvektorheizkörper der eingangs genannten Art, der sich dadurch auszeichnet, dass die jeweils in stirnseitig vorgesehenen, eine Druckkammer bildenden vertikalen Sammelkanäle durch einen Deckel gebildet werden, der formschlüssig mit der gegenüberliegenden Querschnittsfläche der horizontal übereinander angeordneten Rohre des Heizkörpers verbunden ist.According to the invention, this object is achieved by a convector heater of the aforementioned type, which is characterized in that each in provided on the front side, a pressure chamber forming vertical Collection channels are formed by a lid, the form-fitting with the opposite cross-sectional area of the horizontal one above the other arranged pipes of the radiator is connected.

Es zeigt sich, dass eine solche Lösung geeignet ist eine druckdichteIt turns out that such a solution is suitable for a pressure-tight

Verbindung zwischen den horizontal und vertikal verlaufenden Kanälen herzustellen.Connection between the horizontal and vertical channels manufacture.

Vorteilhaft wird dabei die formschlüssige Verbindung durch eingeschweißte Formstücke gebildet wird, die als statische Elemente dienen.Advantageously, the positive connection is welded through Moldings is formed, which serve as static elements.

Vorzugsweise sind dabei die am Deckel angeordneten Formstücke hakenförmig ausgebildete Gegenstücke, die in an der gegenüberliegenden Querschnittsfläche der horizontal übereinander angeordneten Rohre angeordnete Halter eingreifen.In this case, the shaped pieces arranged on the cover are preferably hook-shaped trained counterparts that in on the opposite Cross-sectional area of the horizontally stacked tubes engage arranged holder.

Durch den Einsatz dieser kostengünstigen Teile ergibt sich eine Reduzierung der Herstellungskosten und des Fertigungsaufwandes im Finishbereich.The use of these cost-effective parts results in a reduction the manufacturing costs and the production costs in the finish area.

Weiter wird eine ausreichende Versteifung der Sammelkanäle zur Erhöhung der Druckfestigkeit erreicht. Mit der vorliegenden Lösung ergibt sich weiter eine verbesserte Optik des Heizkörpers, da keine Verschleifarbeiten von Schweißnähten erforderlich sind. Next is a sufficient stiffening of the collecting channels to increase the Compressive strength achieved. With the present solution further results in a improved appearance of the radiator, since no polishing of Welds are required.
